Introduction Congratulations on your selection of the Induction Dynamics S1T 3-way tower loudspeaker. The S1T is engineered for smooth performance and high power handling. The S1T incorporates exclusive, patented S4X crossover and driver-control technology, which makes possible virtually perfect integration of drivers which are ideal for their intended frequencies. S4X also provides greatly increased control over frequency response, phase, and impedance, resulting in superior performance and imaging. Because of S4X technology, any of Induction Dynamics speakers can be used to build a custom home theater system. Your S1T can be combined with any of our center and surround speakers, be they in-wall, on-wall, or free-standing. Your S1T incorporates dual 6.5 Kevlar cone woofers with rubber surrounds and cast frames, a 3 soft dome midrange, and a 1.125 inverted titanium dome tweeter. The S1T is available in Rosewood Gloss, Black Satin, and Black Gloss standard finishes. Custom paints and stains are also available. Grille fabric is available in 63 roomcomplementing colors. WARNINGS: WARNING! - SHOCK HAZARD WARNING! - DO NOT OPEN NO USER SERVICEABLE PARTS INSIDE REFER SERVICING TO QUALIFIED PERSONNEL 2 Audio Perfection Realized
General Information Please read these instructions thoroughly before attempting to connect and operate the S1T. Check Speaker and Parts Unpack and carefully check each loudspeaker. If you suspect damage from transit, report the problem immediately to your dealer and/or delivery service. If possible, save the shipping cartons for future use. General Care of Your Loudspeaker Whenever changing speaker wires, interconnect wires, or power cords, always turn off all equipment. To prevent fire or shock hazard, do not expose the amplifier to rain or excessive moisture. To avoid electric shock, do not open the amplifier. There are no user serviceable parts inside. Your speakers and amplifier come in a high quality finish that is both attractive and durable. To clean, use a soft, damp cloth. If your drivers become dusty, dust them with a paintbrush or a brush vacuum attachment. Do not use a strong or abrasive cleaner. The grille is covered in acoustic cloth. To keep your grille clear of debris, we recommend you use a lint roller (like you would use on clothes). Bass and Loudness Contour Controls Do not use bass or loudness contour controls. Induction Dynamics subwoofers produce very low frequencies without these controls. Use of these controls will make the bass sound boomy, obscure higher frequencies, and possibly cause damage. S1T Location S1T speakers are normally freestanding, but may also be built into walls. The S1T was designed in such a way that the tweeter will be at ear level when the audience is sitting.. The tweeter reproduces high-frequency audio, which our ears perceive as most directional, so we are most attuned to their level and placement. A pair of S1Ts should be placed a few feet from the front wall of the listening area, six feet or more apart. Experiment with the distance between the two speakers to achieve an evenly spread sound stage. Speakers should be at the same height (with the tweeter at ear level). To optimize bass response, vary the distance of your S1T speakers from the front wall. 3
Carpet Spikes Carpet spikes are not required with the S1T. However, they have been provided if you would prefer to use them. Should you choose to do so, lay the S1T on its back side, then screw the carpet spikes into the threaded holes under the base of each speaker. Speaker Wire Use approved wire designed for in-wall or exposed use, as appropriate for your installation. For the S1T, we recommend using high-quality speaker wire that is 12 gauge or lower, with easily visible polarity coding to make your connections. The following chart identifies minimum gauge requirements for various lengths. See your local dealer or installation contractor for more information. 4 Audio Perfection Realized
Speaker Information S4X Crossover The heart of Induction Dynamics is found in the S4X Super Fourth-Order Crossover. The patented S4X inductively couples crossover coils and optimizes each driver s performance, individually and interactively with the other drivers. This greatly increases control over driver range, frequency response, phase and impedance. Because S4X produces such a steep crossover slope and thus a flatter frequency response Induction Dynamics is able to use the best possible drivers for each range of frequencies, allowing us to sonically match every speaker in our lineup and to create speaker models able to perform in any combination and in any acoustic environment. The S4X optimized frequency response means music that moves dramatically up and down in pitch will never fade in or out, but rather maintain its power as it seamlessly crosses over from one driver to the next. It also means that frequencies critical to human speech (frequencies that deliver consonants like S and C ) will sound as natural coming from your speakers as they would in real life making dialogue from movies and television sound crisp and clearly understood. Above: The S4X crossover routes audio signal to their intended drivers at specific frequencies (700 Hz, 3800 Hz). Because the S4X produces such a steep crossover slope, Induction Dynamics is able to use the best possible drivers for each frequency range. Subwoofer crossover points are generally selectable through your subwoofer amplifier. Induction Dynamics recommends a subwoofer crossover point between 50-60 Hz. 5
Wide Angle Phase Alignment In each crossover region, which spans approximately one octave, the sound from two different drivers must be added together. This simple fact creates problems in most speakers, because the phase must be matched, not just on axis, but also off axis in order to create a large sweet spot for the listener. Most speakers drivers are only optimized on-axis, using measurements from a microphone placed at a single point in front of the speaker. This produces a horizontal zone in which the sound is optimized; however there may be drastic differences in sound quality along the vertical axis meaning there may be a loss of sound quality if you stand up, sit, or otherwise move out of the optimized zone. Induction Dynamics eliminates phase differences with respect to height through our Wide Angle phase alignment technology. Because our patented circuitry provides additional variables that can help control phase, Wide Angle finds the one optimization solution that produces a flat frequency response along the vertical axis, when the microphone (or listener s ear) is moved up and down vertically. This means you experience true audio perfection whether you re standing, sitting, or lying down. Conventional Speaker System Wide Angle Phase Alignment Approximate ear level while standing Approximate ear level while seated Approximate ear level while reclining Most conventional speaker designs have a small and horizontally narrow sweet spot caused by inaccurate phase matching of the drivers. The best quality sound can be heard only within a very confined area. Outside of this area the sound quality can drastically decrease, becoming muddy or indistinct. Patented Wide Angle Phase Alignment circuitry provides precise phase matching of the drivers, noticeably expanding the sweet spot both horizontally and vertically. Listeners are immersed in a large sound field and enjoy clear, undistorted sound regardless of their position relative to the speakers. 6 Audio Perfection Realized
Multi-Channel (Home Theater) Installation Speaker Placement 5.1 System A 5.1 system consists of a front left, front right, surround left, suround right, center channel, and subwoofer channel. An S1T generally functions as mains, but may also be used as surrounds. In a home theater configuration, the main left and right channels should be placed a few feet from the front wall as close to listening height as possible. The surround channels should be placed to either side of the listening area or behind the listening area at listening height. 6.1 System A 6.1 system has the same basic channels as a 5.1 system, with the addition of a rear center channel placed directly behind the listening area. 7.1 System A 7.1 system has the same basic channels as a 5.1 system, with the addition of a left rear surround and right rear surround. S1T Speaker Connection Connect the proper output on your home theater processor or receiver to the binding posts on the S1T using normal polarity (red to red and black to black). 7
